Ngokunokwenzeka, ubukholelwa ukuthi ukuthenga ikhadi le-Micro SD noma elinye empeleni bekulinganiselwe ekuthengeni imemori khadi eshibhe kakhulu enomthamo owanele. Nokho, akunjalo. Manje omakhalekhukhwini sebevele besezingeni eliphezulu, futhi bayakwazi ukuqopha nge-4K. Iyiphi imemori khadi ye-Micro SD okufanele uyithenge ukuze urekhode ividiyo ye-4K ngeselula yakho?
Rekhoda ividiyo ye-4K ngekhwalithi
Iselula yakho ingase ikwazi ukurekhoda ividiyo nge-4K. Kodwa-ke, uma ungenayo imemori khadi, ividiyo izogcinwa kumemori yangaphakathi ye-smartphone. Ividiyo ye-4K ingathatha isikhala esiningi, ngakho-ke uma sifuna ngempela ukuqopha amavidiyo e-4K, kuzodingeka sithenge imemori khadi. Futhi uma sifuna amavidiyo e-4K aqoshwe ngekhwalithi, kuzomele sithenge imemori khadi yekhwalithi eyanele. Uma imemori khadi ingenaso isivinini sokubhala esisheshayo, kuyoba lapho sizobona ukusikeka kwesithombe sevidiyo, futhi lokho kungenxa yokuthi iselula ngeke ikwazi ukulondoloza ividiyo njengoba irekhodiwe. Bese, Iyiphi imemori khadi okufanele siyithenge uma sifuna ukurekhoda ikhwalithi ye-4K?
Irekhodi lakho leselula liqopha ngaliphi i-bitrate?
Empeleni kuncike I-Bitrate kuleyo eqoshwa iselula yakho. I-bitrate isilinganiso sevolumu ifayela elisetshenziswayo njengoba likhiqizwa. Isibonelo, i-bitrate engu-20MB/s izosho ukuthi u-20MB uzokhiqizwa isekhondi ngalinye levidiyo. Kuyisibonelo, i-bitrate iyahlukahluka kusuka kumakhalekhukhwini kuya kwenye, kusuka kwikhodekhi yevidiyo eyodwa kuya kwenye, futhi kuncike kumafreyimu ngomzuzwana esiqopha ngawo. Ngokuvamile, okuhle ukuthenga ikhadi elihambisana ne-bitrate ephezulu kakhulu yemodi yevidiyo yekhwalithi ephezulu kakhulu yeselula yethu. Ngakho-ke, ake sithi iselula yethu iyakwazi ukuqopha nge-4K kumafreyimu angu-60 ngomzuzwana. Kuzodingeka sithole kudatha yezobuchwepheshe ye-smartphone ukuthi iyini i-bitrate yevidiyo kuleyo khwalithi ku-smartphone yethu.
Kodwa uma ufunda lesi sihloko kungenxa yokuthi: a) awufuni ukuzenza inkimbinkimbi ukuthi ufunde ukuthi kungani uthenga imemori khadi noma enye; futhi b) ufuna ukwazi ukuthi imaphi amakhadi angaba angcono kakhulu.
Iyiphi imemori khadi okufanele uyithenge?
Nakuba kuyiqiniso ukuthi akunakwenzeka ukusho ukuthi iyiphi imemori khadi ephelele, futhi mhlawumbe amafoni omakhalekhukhwini azokwethulwa ngonyaka ozayo lokhu okuthunyelwe, ikhadi eliphelele ngeke lisaba usizo ekurekhodeni ku-4K (into ezokwenzeka uma omakhalekhukhwini abanekhono bethulwa ukuqoshwa ku-4K kumafreyimu angu-120 ngomzuzwana), singasho ukuthi wonke amamemori khadi ahambisana Ubuchwepheshe be-U3 bungaba usizo ekurekhodeni nge-4K. Amakhadi asekela ubuchwepheshe be-U3 anelogo ekhadini ngokwalo, okwenza kube lula ukulithola. I amamemori khadi anelogo ye-U3 aqinisekisa ukuthi isivinini sokubhala sidlula u-30MB / s.
Ukurekhodwa kweselula ku-4K kumafreyimu angu-30 ngomzuzwana kuzoba ne-bitrate ephakathi kuka-30 no-60 Mbps (ama-megabits ngomzuzwana). Ukukhumbula ukuthi ibhayithi ingamabhithi angu-8, kufanele nje uhlukanise ubukhulu ngo-8. Sidinga isivinini sokubhala esiphezulu esingu-7,5 MB / s. Amakhadi ane- Ilogo ye-U1 iqinisekisa ukuthi banesivinini sokubhala esidlula u-10 MB / s. Baphinde bangamakhadi e-Class 10, anophawu lwe-C10. Ngokuvamile, imemori khadi ingaba nawo wonke ama-logo ahlukene.
Uma uthenge okuphambili kwakamuva emakethe, engikuncomayo ukuthi uthenge ikhadi elinelogo ye-U3. Singathenga ikhadi elinjalo ngentengo engaba ngama-euro angama-55, nge-64 GB yomthamo. Uma uthenge iselula ebiza kangaka, into enengqondo ukuthi uthenga imemori khadi yekhwalithi. Uma uthenge iselula yebanga eliphakathi, thenga ikhadi le-Class 10 elingabizi. Kulokhu, kungenzeka ukuthola amakhadi angama-32 GB cishe ngama-euro ayi-15. Ngisho noma iselula yakho irekhoda i-4K, kungenzeka kakhulu ukuthi ayisoze, ngisho nangesibuyekezo, irekhode i-4K kumafreyimu angama-60 ngomzuzwana, ngakho-ke ngeke udinge imemori khadi enejubane eliphezulu lokubhala.
